1983年底第三代稀土永磁材料 Nd-Fe-B 的研制成功好象在永磁材料领域升起一颗明亮的彗星,立即引起全世界的注意.很多国家已开始组织生产.与此同时对R2Fe14B金属间化合物的基础研究也形成了世界范围的热潮. 物理研究所在几个课题组密切配合下,经过近一年的努力,解决了一些关键性 The successful development of Nd-Fe-B, the third generation of rare earth permanent magnet material, at the end of 1983 seems to have raised a bright comet in the field of permanent magnetic materials, arousing the world’s attention immediately. Many countries have begun to organize production. The basic research of R2Fe14B intermetallic compounds has also formed a worldwide boom.Physics Institute, with the close cooperation of several research groups, solved some key problems after nearly a year’s efforts
